Structural Characteristics Of Small Rotary Dampers

- Sep 13, 2017 -

      The concrete structure of the rotary damper is based on a standard gear, the shape of the gears is gradually open, the gears of this shape can run well, even the excellent operation. It uses 20 degree pressure angle, diameter is about 0.35, material is shell and polycarbonate, gear material is acetal. It can be seen that gear-centered, torque and shaft-assisted, is the formation of a rotary damper.Small Rotary Dampers

      Speed: The torque is also changed according to the change of rotational speed of the rotary damper. The change law is as follows: The speed is increased and the torque is increased. The speed slows and the torque drops. The torque differs from the standard torque when starting. Temperature characteristics: Rotating damper According to the use of ambient temperature changes, the torque has also changed. The change rule is as follows: when the ambient temperature increases, the torque decreases and the ambient temperature decreases. This is because the viscosity of the viscous oil in the damper changes as the ambient temperature changes. However, when the ambient temperature is restored to normal temperature, the torque is restored to its original value.Small Rotary Dampers

      A pulsating damper is a pressure vessel used to eliminate fluid pressure pulsation or flow pulsation in a pipeline. Can play a stable fluid pressure and flow, the elimination of pipe vibration, protection of downstream instrumentation and equipment, increase pump volume efficiency and so on. Airbag type: The use of inert compressed gas in the airbag contraction and expansion to absorb the pressure of the liquid or flow pulsation, this kind of pulsating damper is suitable for the pulsating frequency is less than 7Hz applications, because if the frequency is too high, the diaphragm or airbag can not respond to the effect of eliminating the pulse.Small Rotary Dampers

    No moving parts: the use of solid medium to intercept the fluid directly to achieve the buffering pressure pulsation or flow pulsation effect, this kind of pulsating damper is suitable for high-frequency pulse application. To select the suitable pulsating damper, it is necessary to determine the target of the pulsation cancellation rate according to the actual situation and the process requirement, then the quantitative selection is carried out according to the technical index. Small Rotary Dampers

    Accurate pulsation Damper selection should be based on flow, pressure, pump type, pump speed, pump cylinder number, pump phase difference (multistage pump), pulse elimination rate, application purposes, pipeline fluid composition, pipeline fluid density, pipeline fluid viscosity, pipe fluid temperature parameters, such as comprehensive calculation and analysis of the determination.Small Rotary Dampers
